    <p>Dear stackoverflow folks! To this day I never saw the need to ask a question, because all of you have done a great job in asking and answering nearly all of the code-related problems I encountered. So, thank you for that!</p> <p>At the moment I am working on an iOS application that is able to process raw touch events. These are then sent to an iMac over a WiFi network (the protocol I use is OSC). On the OS X side there is a server application listening for these OSC messages and converting them to mouse pointer movement / mouse button press / multi-touch gestures. So basically I want to build a (of course much more basic) software-bundle like mobile mouse (<a href="http://mobilemouse.com/" rel="nofollow noreferrer">http://mobilemouse.com/</a>) that I am able to adapt to the needs of our customers (by the means of customizing colors / additional buttons / gestures, and so on) for small remote control projects.</p> <p>Right now, everything works but the multitouch gestures (pinch, rotate, two-finger-scroll). So my question is: <strong>How can I programmatically create and post a multitouch gesture event?</strong></p> <p>I searched a lot and found some threads about it here on stackoverflow, but none of them could help me: <a href="https://stackoverflow.com/questions/2487331/is-there-a-way-to-trigger-gesture-events-on-mac-os-x">Is there a way to trigger gesture events on Mac OS X?</a> - <a href="https://stackoverflow.com/questions/10799666/is-there-a-way-to-change-rotation-of-gesture-events?lq=1">Is there a way to change rotation of gesture events?</a> - <a href="https://stackoverflow.com/questions/6699165/generate-and-post-multitouch-events-in-os-x-to-control-the-mac-using-an-external?lq=1">Generate and post Multitouch-Events in OS X to control the mac using an external camera</a> - ...</p> <p>Update 1: The last thing I tried was:</p> <pre><code>CGEventSourceRef eventSource = CGEventSourceCreate(kCGEventSourceStateCombinedSessionState); CGEventRef event = CGEventCreate(eventSource); CGEventSetType(event, NSEventTypeMagnify); CGEventPost(kCGHIDEventTap, event); CFRelease(eventSource); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
